SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 482,111, datedSeptember 6, 1892.

Application filed May 20, 1892. Serial No. 433,693. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES L. WALTERS, of Seabright, in the county ofMonmouth and State of New Jersey, have invented a new and usefulImprovement in Blind Fasteners and Adjusters, of which the following isa specification.

My invention consists of an improved blind fastener and adjuster whichwill securely lock the blind at any desired angle to its support, willprevent any rattling of the parts, and will make it impossible for theblind to become unhinged by heavy winds or other causes. I also providesuch a construction that the curved bar may be easily and quicklyadjusted so as to be made substantially concentric with the hingedconnection between the blind and its support.

A practical embodiment of my invention is represented in theaccompanying drawings, i n which Figure 1 is an interior view of aportion of a blind and window-casing, showing my fastener and adjustersecured thereto, the'blind being represented as fastened in its closedposition; and Fig. 2 is a top view of the fastener and adjuster, showingthe blind and window-casing in section, the blind being secured at anangle from the casing. V

A designates the side of the Window-casing, and a the sill.

B is the blind, and it is hinged at one side to the casing A, as isusual.

0 is a curved bar or rod of any suitable shape in cross-section, and itis adj ustably secured at one end in a socket-piece D,which is fastenedto the outside of the building or window-casing in any suitable manner.The other end of the curved bar 0 is adjustably secured in asocket-piece E, which is fastened to the sill a of the window-casing. Inthe present instance the rod 0 is shown as secured in the socket-piecesD and E by means of screws d and c. This curved bar is semicircular andis adjusted in the sockets D and E, so as to be substantially concentricwith the pivots of the hinges upon which the blind B swings whether thehinges are spaced a greater or less distance from the casing.

A plate F is secured to the inner face of the lower cross-piece of theblind B. A horizontally-elongated slot f is formed in the plate F andblind B, through which passes the curved bar 0. The object of formingthis slot elongated is to allow the blind to swing freely back and forthwithout binding upon the rod 0 if the rod has not been adjusted so as tobe exactly concentric with the pivots of the blind-hinges. After the rod0 has been passed through the slot f and secured in the socket-pieces Dand E it is impossible to unhinge the blind, it being held from anyvertical movement by the said rod.

The means I employ to secure the blind at any desired angle in relationto the support is as follows: A lever G is pivoted to the plate F inposition to press upon the curved rod 0 when forced down by a cam-leverH. The lever G is held normally away from the rod 0 by means of aspring-arm g, which abuts against a stop g on the plate. The cam-lever Hisprovided with a projection h, which rests against the end of the leverG when the cam-lever is in its raised or open position.

When it is desired to lock the blind, the cam-lever H is depressed andthe cam thereon engages the top of the lever G and forces it down uponthe rod C. When the blind is locked in its closed position, as all thesecuring mechanism and one of the socket-pieces are on the inside of theblind it is impossible to open the blind from the outside. By thisinvention the rod. 0 may be made without indentations or recessesthereon, and therefore much stronger and simpler than heretofore, andyet the blind may be securely fastened at any desired angle.

It is evident that slight changes might be resorted to in theconstruction and arrangement of the several parts without departing fromthe spirit and scope of my invention. Hence I do not wish to limitmyself to the exact construction herein shown; but

What I claim is r In combination, a support, a blind hinged to thesupport, a plate upon the blind, said blind and plate having anelongated slot therein, a curved bar passing through said slot and adjustably secured at both sides of the hinged connection between the blindand the support, and means for securing the blind to the bar atdifferent angles, substantially as set forth.

CHARLES L. WALTERS.
